The long, slender projection of a neuron that conducts electrical impulses away from the neuron's cell body.
An organism's external reaction to its environment.
The brain's ability to change and adapt as a result of experience.

The neuron that fires when a human observes and imitates the same action made by another.
Forming new neural connections are the brain develops
The process by which neural connections that are no longer needed are removed due to the strength of the connection
A specialised nerve cell that receives, processes, and transmits information to other cells in the body.
When an electrical impulse travels down the body of a neuron (axon body), it releases neurotransmitters which cross the gap between two neurons known as the synapse
A chemical messenger in the brain that stimulates a range of physical and psychological processes.
The visual processing area of a mammalian brain.
Hormone released by the pituitary gland and is responsible for human behaviours associated with relationships and bonding - e.g. the love hormone
Chemical signals that are released by both animals and humans that send olfactory (scent) messages to other members of their own species.
A neurotransmitter that is involved in with sleep, depression and memory (along with other psychological processes)
The junction between two neurons where there is a small gap that neurotransmitters help nerve impulses to cross.
Process by which more synapses are generated as an individual encounters new stimuli.
The part of the brain that is able to understand and recognise language. Located in the rear of the left temporal lobe.
